Abstract
A reciprocating double moving cutter cutting test device comprises a cutting mechanism, a stalk feeding mechanism and a monitoring operation mechanism. Input power of a motor drives, through a connecting rod, an upper cutter rod and a lower cutter rod to move parallelly in different directions so that an upper blade and a lower blade which are adjacent move, are staggered and overlapped, and cut crops. A torsion rotating speed sensor is arranged on a power input shaft. A pull force sensor is arranged between the upper cutter rod and the lower cutter rod and a left rocker arm and a right rocker arm. A rotating speed sensor is arranged beside a transmission wheel. The torsion rotating speed sensor, the pull force sensor and the rotating speed sensor are used for inducting and recoding parameters in cutting processes. A best parameter combination is calculated through a computer. According to the reciprocating double moving cutter cutting test device, two layers of moving cutters simultaneously move in the different directions at the same speed, and inertia force of the upper cutter rod and the lower cutter rod is offset, so that a cutter is prevented from producing severe swings; and one connecting rod is used for transmitting power so that accuracy of motion of the upper blade and the lower blade is improved, and installation and debugging processes are reduced.
